E7 is zero one gold anchor behind zero one silver shield. for E8, E9 and even E10 its the same just add the correct amount of silver stars above the shield.
O7-O10 is a field of gold. O7 is zero one silver star below zero one anchor behind zero one shield on a field of gold. 08-O10 is the same just add stars accordingly.
now, this is all just the base of how to describe the stuff. when we meet our CCs they might have us say certain things differently but the main idea is there. anchor behind shield below star.
